Because there can be bugs and other issues like mold, fungus, weeds, stray seeds, etc, the pucks, cubes and rooters start out sterile. I note some plants root faster in the Rapid Rooters than they do with the rockwool or visaversa, depends on the phenotype.

I worked very hard over a 2 year period to rid myself of gnats, mites, and any other bug issue. Now I only use sterilized out of the bag stuff.
